Synthetic approaches to pentacyclic triterpenes of the arborane family

Synthesis, from 2-methylcyclohexane-1,3-dione and 2-methylcyclopentane-1,3-dione, of optically pure bicyclic intermediates representing the A/B and D/E fragments required for an approach to isoarborinol.

An unexpected (3 → 2)-hydride shift in phyllocladane (=13β-kaurane) diterpenoids and in related trimethyl-substituted Bi- and tricyclic compounds

The conversion of 2α,3α-dioxy-substituted phyllocladane derivatives into the corresponding 3-ketone proceeds in an unexpected manner: Depending on the reaction conditions, the corresponding 3β-hydroxy-substituted compound is formed almost quantitatively,
